I wonder even if a widget builder is the right approach. If one
can program some advanced stuff in IDL, she/he is very likely able
to create a proper widget interface to the program.
From my point of view, widget programming is not hard but only
writing some lines of code more than you may have wished. But
do it yourself (and not with a GUI builder) ensures that the
code can be maintained afterwards.
What I really suggest is to have a look at all the CW_*
(compound widgets) routines. These provide lot of things commonly
used. Maybe/Hopefully some nice CW's are added (something for
defining a region of interest, a wrapper around the trackball,
...)
Something different:
If IDL continues its OO way (and I completely support this decision)
they should really think about getting support by 'Rational Rose' (RR),
which is a oo-development 'tool'. This would increase its acceptance
by people which even have not even thought to use IDL (and if this
people can afford RR, they also can afford IDL)
Why in this context? Then it is easy to create a widget interface
and the accompanying code simply by using the GUI of RR to >define<
the program [and let RR write it then].
